Before placing a call, it is quite often useful for the Caller to
know whether a Callee is in favourable state to receive a call or
not. This document defines an optional tag "continue" and a header
"Continue" to address the purpose. The "Continue" header field is
to confirm the session continuity with the Callee from the Caller
after an option for session continuity is placed by the Callee based
on the unfavorable state of the Callee. This functionality is needed
to resolve the unwillingness of the Callee to receive any call. An
option is given to the Callee by the Service Provider or by the
Handset Manufacturer or by the Carrier to establish this requirement.
